一種新穎的高頻鏈逆變器

摘要：本文結合推挽正激直流變換器和高頻脈沖直流環節逆變器的優點，提出了一種適用于低壓大電流輸入場合的逆變器，并對構成這種逆變器的電路拓撲、SPWM控制策略、穩態原理特性進行了深入的分析研究。實驗結果證明，該逆變器具有結構簡單，效率高，輸出電壓質量高等優點，是低壓大電流輸入逆變器的理想拓撲。 敘詞：逆變器，推挽正激，正弦脈寬調制 Abstract： An inverter with high frequency link that suits for low input voltage is proposed in this paperIt has advantages that exit in push-pull forward DC converter and high pulse direct link inverterThe circuit topology, control strategy of SPWM, and steady principle property,are deeply investigatedThe experimental results show that the inverter has advantages of simple construct,high efficiency and excellent outputting voltage and it is a novel topology for low voltage and high current inputting inverter Keyword：Inverter
